I have additional insurance on all of my quilting "STUFF". Machines, tools, fabric , books, tables ... all of it. Check with your agent some polices will cover .. but to a limit. Whe I was talking to mine he asked me what the valuation/replacement value would be ... He was stunned at the $$$ . He said "this I have to see" , when you took a look ..he said "this isn't that much". I then pulled off a stack of fabric and told him each fabric represented ruffly $10.00 and there was about 20 in the stack... He quickly did the math for just fabric ... then we moved on to machine with all the accesories... before we got to the books etc ... he stopped me and said "you need additional coverage". It is in part because my studio is in the basement ..and my policy limits the claim for basement water damage( most policies do limit basement coverage) .
